description
The MPT57571 is a source driver LSI that drives an active-matrix LCD panel, as well as a 256-gradation driver
that implements multi-pin configuration and reduced power consumption.
The MPT57571 has 384 panel-drive outputs. Because it is expandable, the MPT57571 is used in multiple
applications, the screen can be enlarged, and the L/R (shift-direction switching) terminals simplify LCD panel
interconnection.
The device has a large output dynamic range (13.1 V ) that makes the reverse driving of opposing electrodes
PP
in the LCD panel unnecessary. This reduces system power consumption and produces a high-quality picture.
The device is also compatible with single-sided mounting, dot reverse driving, and source line reverse driving.
The MPT57571s 384 outputs ensure XGA/VGA compatibility, making it useful in a wider range of applications.
The maximum operating clock frequency of the MPT57571 is 55 MHz when the power supply voltage for the
logic section is between 2.5 V and 3.6 V and the single-side driving of an LCD panel has been implemented.
